To all whom t may concern.'

Be it known that I, CAssIUs M. PARsoN,

a citizen of the United States, residing at Kokomo, in the county ofHoward and State of Indiana, have invented certain new and usefulImprovements in Window-Screens, of which the following is aspecification.

y invention relates to an improvement in window screens, and morearticularly to that type of screen intended finir use by having the wirefabric thereof mounted upon a spring roller with the loose end attachedto the window sash so that as the sash is moved the screen will beextended from or taken up by the spring roller.

An object of, my invention is to provide a structure of the character'as set forth which is of such form and construction that the parts maybe embodied in conjunction with the framing of a window as the window isbeing installed as new may be built into an old window.

nother object lies in providing a spring roller which 1s so formed thatit partakes substantially of the character of the usual shade roller,but has no means forcatching to hold the roller against turning underthe action of the spring, the parts being thus so arranged that as thewindow is either raised or lowered in a sliding path the spring of theroller will permit ready extension of the screenA or will take the sameup properly.

Yet another object lies in providing means by which the roller is heldagainst movement under the impulse of the spring during the installationin conjunction With a window, and in constructing means by which theroller will be removably held in place but may be positively secured tobe retained against accidental or casual displacement.

Vith the above and other objects in view, my invention consists incertain novel features of construction and combinations of parts whichwill be hereinafter set forth in connection with the drawings and thenmore particularly pointed out in the claims.

In the drawings Figure 1 is a View in elevation showing a Window with myinvention applied thereon.

Fig. 2 is a vertical the line 2-2 of Fig. 1. v

Fig. 3 is a view showing the springroller and with the arts illustratedin sectlon.

Fig. 4 is a fi'agmentary view taken on the line 4 4 of Fig. 3.

Fig. 5 is a detail work, or the parts,

sectional view taken on view in section taken on the line 5-5 of Fig. 3.

Fig. 6 is a detail view showing a modification which might ber-resortedto in the construction of the spring roller mounting. v

- The window frame which is formed to embody the side casing members 1and 2 with the lintel 3 and sill 4 connected therewith is substantiallyof standard form and has the upper and lower sashes 5 and 6 mountedtherein to be capable of sliding movement. To all intents and purposes,these parts are of usual construction, but in the roughing in of theframing around the window, clearance is to be left above the lintel andbelow the sill.

The lintel is slotted through as shown at 7, adjacent to the outer edgeof the upper sash, and the sill 1 has a similar slot 8 provided adjacentto the inner side of the lower sash. Roller supporting brackets 9 and 10are mounted at the sides of the frame adjacent to the slotted openings 7and 8, by being secured on the side casing members 1 and 2 if desired,and these supporting brackets are made of substantially the type nowordinarily used for shade rollers, the one being provided with asubstantially circular orifice and the remaining ing anotch formedtherein, after the manner shown at 11 in Fig. 4.

Spring rollers 12 and 13 are mounted in these brackets 9 and 10 toextend across above the lintel 3 and below the sill 4, and to lie'inparallelism with the openings 7 and 8. These spring rollers 12 and`13,which are substantially duplicates, comprise the wood, metal, or othercylindrical body portion l1 cored out or otherwise shaped at one end toprovide the socket or opening 15. At the opposite end of the body 14, abearing pintle 16 is secured by being driven into the body, or in anyother manner, this bearing pintle being of substantially cylindricalform so that it may be inserted in the circular opening of the onesupporting bracket and will turn freely therein. A block 17, which has abearing provided therein for the spring mandrel 18 is shaped to bereceived in the bore or opening 15, and a pin 18 is provided to holdthis block against turning Within the opening. A coil spring 19 isconnected at one of its ends with a block 17 and after being woundaround the mandrel 18 to substantially the bracket of each pair havvouter 0nd thereof is secured 110 ybrackets 10. This fitting of the flatsided portion of the mandrel within the notch 11 will mount the mandrelto be held against turning movement with respect to the supportingbracket, and thus the sprlng 19 has full control over the roller body.To secure the mandrel 18 against displacement from the notchvll,a-substantially hooked shaped member 22 is carried on the supportingbracket 10 .to be brought down over they mandrel after the same has beenmoved to occupy a position at the bottom of the notch 11.

The rollers 12 and 13 have the wire mesh or other screen strips 23 and24 connected thereon and then wrapped around the rollers, and at theirfree `ends these screen strips are connected with the upper and lowersashes respectively, it of course being under- Stood that the connectionwill be made with the top and bottom rails of these sashes. The screenstrips are extended through the slots 7 and 8 previous to securement tothe sashes and to insure that the fabric will not pull out, reinforcingstrips 25 may be placed over the connected edges as the screen stripsare attached to the upper and lower sashes.

The parts can be assembled when the window is being built by mountingthe supporting brackets 9 and 10 in the proper relations before theframe is set in place, and then placing the rollers 12 and 13 in theirproper positions before application of the interlor trim, it of coursebeing understood that the sashes must be first fitted to work properlybefore the screen strips are brought through the slots 7 and 8 and areconnected therewith. lVhile the rollers 12 and 13 are being fitted inplace, it will be desirable to mainf tain the springs 19 in a partiallywound condition, and as no catch means is provided, the parts .asillustrated in Fig. 5 might be employed. As is here shown, the mandrel18 is provided with a transversely extending bore 26 and a short lengthof,w1re 27 is inserted in this bore 26 and is then brought around andfastened in the opening 28 in the cover plate 20, this length of wirethus securing the mandrel against turning movement under the impulse ofthe spring 19 after the mandrel has been turned to store up energy inthe spring.

Where the screen structur'eis to be fitted to a window already built in,and even in as some instances where windows are being newly placed, itmay be awkward to apply the bracket portions 9 and 10 in the manner asabove set forth, and-therefore under these circumstances the supportingbrackets can be formed after the manner shown in Fig. 6 with thesupporting and attaching base thereof bent substantiall f at rightangles to the main extent. The brackets 29 are then secured at theproper points upon a supporting base strip 30, which is made ofcomparatively narrow width and which may thus be inserted through a slotleft or cut through the lintel and the sill. Following the insertion ofthe parts, the cut away portion can be inserted in place and then screwscan be used to secure the supporting base bar 30 in the proper mounting,it of course being understood that the screws will be passed throughfrom the outer side of the lintel or sill to draw the base portion 30tightly y thereagainst.

From the foregoing it will be seen that a screen structure is providedwhich disposes the screen portion in such relation that when the windowsare closed, the screen strips are entirely concealed, and as either sashis moved, the screen strip carried thereby is brought to cover over theopening as left by the shifting of the sash, that the parts as describedmay be fitted in conjunction with a window as the saine is built in ormay beapplied to windows already in place without material alterationand without destruction to the standing woodwork or trim of the window,and that the rollers as provided are at all times positively maintainedin the proper relation and operate to let out and take up the screenstrips to insure that the same will be tightly stretched over theopening at all times while at the same time the movement of the sasheswill not be interfered with except in so far as the force of the springis concerned; and, that the arrangement-of the parts in the manner asset forth is such that when the sashes are brought to the closedposition, the screen strips will be rolled smoothly upon the rolls tothus be maintained against bulging or uneven stretching and will beprotected from the Weather.

The sash may have window lifts 31 secured thereon to aid in the raisingand lowering, and if desired a strip 32, which may be of felt, rubberfabric, or other suitable material can be secured on one of the sash toform a stop as the two sash are brought to intermediate position, itbeing preferable that this strip be secured on the lower side of thebottom rail of the upper sash as in this mounting the strips 32 willexclude iies or other insects from finding their way up between the twosashes. It will of course be understood that the screen strips 23 and 24are to lit over at their edges rather snugly against the side casingportions 1 and 2, and

nasceva thus tiies and other insects will be excluded at these points.

lli/while in the foregoing l have shown and described only specificforms of construction, it will be understood that this structure mightbe adapted for use in hospitals and in other places by having fabricinserted in place of the screen strips to thus permit passage of air butto cut oil' strong currents of air or draft, and that a number of otherchanges and modifications might be resorted to in the torm andarrangement of the sev eral parts as in the manner of application,without departing from the spirit and scope of my invention and in viewof this tact l do not wish to be limited to the exact disclosure butonly to such points as may be set forth. in the claims.
